SPECIFICATION formng' part of Letters Patent No. 281,*786, dated July24, 1883 Application filed March 29,188& ago model To all whom it may0012067 77,

Be it known that I, CHARLES NELsoN, of East New York, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Slate-Frames, of which the following is a specification.

This invention has reference to an improved slate-frame of that class inwhich is applied around the circunference of the frane a noise muffiingedge-strip, that projects at both sides of the frame; and the inv'entionconsists of a slate-frame around the circumference of which is applied anoise-muifiing edge-strip coniposed of an interior core of wood havingcords at both edges, the core and the edge-cords being covered bycontinuous braiding, and then securely attached to the slate-frame.

In the accompanying drawings, Figure l represents a side elevation of myimproved slate-frame; Fig. 2, an end View; and Fig. 3, a Verticaltransverse section of the same on line x x, Fig. 1. Similar letters ofreference indicate corresponding parts.

A represents awooden slate-frame of the usual Construction, that isrounded off at the corners.

Around the entire' circuniference of the slate- 1 frame A is applied anoise-muffling strip, B, which is composed of a core, b, of wood, thatis made straight at the side adjoining the outer edge of the slate-frameA, slightly conVeX at the outer side, and straight at the edges, asshown clearly in Fig. 3. The edges of the The strip b is nade equal inwidth to the thickness of the slate-frame, the edge cords and braidingcausing it to project at both sides of the same, so as to form a supportfor the slateframe and produce a muffling and protecting action for theslate. The muffling-strip B is nailed or otherwise fastened to theslate-frame, as shown in Fig. l, and made of such a length as to extendaround the slate-frane, the neeting edges of the strip B being neatlytrinmed, so as to fit accurately together. They are then covercd by apiece, e, of ribbon or other suitable fabric, that is also nailed to theslateframe, as shown in Figs. "l and 2.

I am aware that a slate-frame provided with an edge-strip that projectsat both sides of the frane is old and has been used heretofore, and I donot claim this feature, broadly.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with a slate-frame, of anoise-mufiing strip,which is applied around the circumference of thevframe, and is .composed of an interior core or strip of wood having acord at each edge, said strip and edgecords being covered by continuousbraiding, substantially as' set forth.

2. A noise-muffling strip for slate-framcs, composed of a core or stripof wood, havinga cord at each edge, and of a covering-braid exrtendingcontinuously over .the strip and edgecords, 'substantially as set forth.

In testimony that I clain the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

CHARLES NELSON.
